The CephCluster resource will now expose the health of the ceph cluster so admins can query the status with k8s api or kubectl instead of needing to run the rook toolbox. The operator will query the ceph status periodically and update the status in the custom resource. Signed-off-by: travisn <tnielsen@redhat.com>
